Description of problem:
ia64/IPF (rx2600) system reboots during execution of "tar cvf fullbackup.tar /" command. The culprit is /proc filesystem. If the tar
command excludes the /proc filesystem, the tar command is successful without a system reboot.

memory locations you will MCA. For example, just wc /proc/kcore you will generate an MCA and reboot.
